My kids like the bath, but they like taking a shower with me. Even before they could stand and walk (but could sit and play) they went in the shower with me. They loved it. They would play in the corner of the shower while I cleaned myself and then I would use the baby wash and give each a shower in turn.
They are now 5 and 3 and often both want to join me in the shower. They still play while I shower and then each gets washed after. Works like a charm, except there isn't much room for me now.
We only have a shower in our RV and it is small. I usually wash one at a time and just keep the shower door open. We do have a shower sprayer that has an on/off switch, so we can stop the water flow without having to readjust water pressure/temperature each time. I just turn off the flow at the shower head, soap them up and turn it back on to rinse them off.
Good luck to you. I would save the bath experience for special occasions when you visit family or stay in a hotel. Do be careful to rinse her vaginal area very well to avoid possible infections from the soap and/or sweat and pee.
